it has the name saying that its the SHIKI SPECIALS but i think it just another two episodes that is absolutely 100% necessary for the story so do all a favor watch it in order or you will be confused if you watched it after the SHIKI.this is episode 20.5 and 21.5 watched it in that order when your watching the story because these episodes make the plot complete and it makes perfect sense how everything was handle at the very end.so enjoy ! i have said everything i have to say in the previous review.this anime made me fall in love with anime allover again and im so much in love with it if thats even possible.i love my life :3
